I guess the deal with vulgarities and I is that, it just flows out pretty easily now.
That's a pretty bad sign so I figured I should probably stop it.
Maybe sometime soon. LOL.
So anyway I was playing yesterday and there happened to be some war going on between some people.

And when you see that, you know it's definitely a Singaporean.
That's pretty sad considering how easy it is to identify it.
I think these typical remarks follow a standard procedure, and it's probably something like this:
1. Be firm about your stand. Insist the other party is wrong no matter what.
2. Have bad spelling.
3. Insert Hokkien. This is a must.
4. Mix Singlish together with Hokkien.
5. Always remember to scold the person's mother, no matter how unrelated the issue is to her, or how innocent she actually is.
6. Be violent. Mention a one-on-one at any given opportunity.
Oh, and when you suggest [6] and the other party declines, do [7]:
7. Provide your address and challenge the person to find you to settle it in real life. Even if it's not even a major issue.
And if the person declines both [6] and [7], begin insults about him being a coward. This is where [8] comes in really handy:
8. Include as many body parts as possible. Best when used in Hokkien. For example, "y dunwan. bo lanjiao issit. cb."
I think that's basically it.
It's actually not that difficult, so try it yourself! :D
